Method for the handling of parent reels in paper converting plants, comprising the following steps: (a) providing at least one platform with a base adapted to support a parent reel in a waiting station and at least one unwinder (S) adapted to receive said reel in an unwinding station where the parent reel is unwound; (b) positioning a parent reel (1) on the platform at the waiting station; (c) transporting the parent reel (1) along a predefined path from said platform to said unwinder (S) by means of a bridge crane (CP) equipped with movable arms (BC). The step (c) is preceded by a first step consisting in the temporary association of two pins (P) to the arms (BC) of the bridge crane (CP) and by a second step consisting in inserting the two pins (P) in two opposite bases of the parent reel (1) using the same arms (BC); and the step (c) involves the transport of the reel (1) along a path comprising at least one ascending or descending portion with the pins (P) thus inserted into the parent reel (1).

A reception sleeve that may be mounted on a mandrel of a packaging machine for winding up a film used in the packaging process on the reception sleeve. The reception sleeve may include a plurality of hinges. Each hinge may have a hinge axis, wherein each hinge axis may be oriented in a direction parallel to a central axis of the reception sleeve. The reception sleeve may be mounted on a reception mandrel of the packaging machine, preferably for winding a residual film grid remaining after sealing trays in the packaging machine. The mandrel may include a mechanism for selectively tensioning the reception sleeve thereon to tension the reception sleeve to allow the mandrel to transfer a winding torque to the reception sleeve, and to reduce the tension so the reception sleeve can easily be removed from the mandrel.

An apparatus for the accumulation of wire or cable, the apparatus including a collapsible reel assembly, the collapsible reel assembly including a central hollow arbor, a fixed inner support structure axially centered on and rigidly attached to the central hollow arbor, wherein the fixed inner support has a first end and a second end, a fixed flange, axially centered on and attached to the first end of the fixed inner support structure, a removable flange, axially centered on and removably attached to the second end of the fixed inner support structure opposite the fixed flange and an inner drum assembly. The inner drum assembly including a plurality of moving inner support structures movably attached to the fixed inner support structure and a plurality of inwardly-collapsible drum segments. Wherein the inwardly-collapsible drum segments collapse inward after the removable flange is removed from the collapsible reel assembly.

A pair of flanges attachable to the arbor hole of a reel is disclosed. The flanges provide a mechanism to allow the reel to be easily loaded, and lifted into place. Once loaded into place, the flanges may include a locking mechanism that locks the reel in place, centered on the flanges. Additionally, the flanges are attachable using a hub that allows them to rotate independently from one another, and from the reel to which they are attached.

The inner drum assembly including a plurality of moving inner support structures movably attached to the fixed inner support structure and a plurality of inwardly-collapsible drum segments. Wherein the inwardly-collapsible drum segments collapse inward after the removable flange is removed from the collapsible reel assembly.

A linear body that may be smoothly removed from a bobbin. The bobbin includes a guide tube, a pair of flanges provided on the ends of the guide tube, and a winding drum sandwiched between the pair of flanges. One flange is removably attached to one end of the guide tube and the other flange is fixedly secured to the other end of said guide tube. The winding drum includes a plurality of split drum plates separated by a plurality of slits. A biasing mechanism for biasing each split drum plate inwardly is provided. When the detachable flange has been attached, the split drum plates are supported at both ends from the inner side thereof by supporting projections on the inner surface of each of the flanges. When the detachable flange is removed, the split drum plates move inwardly owing to the respective biasing mechanisms.
